a bit confused on my 78 gs1000 R/R

[BassCliff]

Unless there is a sense wire either SHUNT or SERIES will regulate voltage internally so a voltage drop from R/R(+) to battery (+) will cause the same mis charging of the battery. Same applies at the negative side.

Thank you for keeping us on our toes Jim. I appreciate you expertise. I guess it's just a good idea to have clean connections everywhere regardless of which r/r unit you are using.


Thank you for your indulgence,

Hi,

I don't want to get in the way of Mr. rustybronco. I just want to share this.



You will toss the old separate rectifier and regulator units. Connect the three output wires from the stator to the input wires on the new r/r unit. As stated in The Stator Papers, the stock Suzuki stator had different colors for the output wires but just consider them all "yellow" because the order doesn't matter how they are connected to the input wires on the new r/r unit.

Then green is ground, black is the "sense" wire, and red is the regulated output.

You may have a loop going up to a headlight switch on the handlebar. This can be disconnected and covered. I think it's explained in the Stator Replacement guide on my little website.

Hi,

I don't want to get in the way of Mr. rustybronco.

You're not...

the '78's 'Y' off two of the stator wires and as such one wire of each pair is redundant.

78gs1knh and I will discuss the connections and his modified harness when he gets the R/R from Duaneage. that and whatever else I can stick in His(?) head.

I guess i just feel a bit slow today...

Totally figured it out. the Y splits arent going to matter anyways since its one unit. the Y's just go back to the stator. (Man, do i feel dumb.) Came to this conclusion after re-reading the rectifier checks in the manual... how i did not see that is beyond me... Fig 11-13 really opened my eyes, Haha. I'll let you know how the install went!

Thanks again, and sorry for the confusion and lack of experience... maybe one day i'll have a finished product

ran some more tests on the stator yesterday to make sure the thing didn't fry from the bad OEM R/R, and just as i thought, the thing has continuity on every leg... no resistance at all between yellow wires. (from what I've read it should have at least a .5 ohm resistance) ordered a new ricks stator to go with this R/R kit, so hopefully with an entirely new charging system i shouldn't have any issues in the near future

Continuity is GOOD in the legs of the stator.

Just so you don't get confused, even 1000 ohms is "continuity". Zero ohms is also "continuity".
When wires are connected, the circuit is "continuous" and current can flow.

What you DON'T want is a break in the stator legs or continuity from any of the legs to a ground point.

Am i reading the stator papers and stator checks incorrectly in regards to each leg having no resistance between them? (when they state they should have at least .5-2.0 ohms?)
I'm an electrical newbie... for some reason I've always had difficulty with it...

Hi,

You are reading it right. If you get 0.0 ohms between legs then the windings are shorted, probably due to melted insulation on the wires. Shorted windings do not produce AC, which is bad for charging systems and other living things.

Like Mr. Steve says, "continuity" is just a fancy word for a "connection". Connections can have different resistance values.

This is a timely thread: Why Unloaded Stator tests are BAD.

Be very careful making sure your leads make good connections when checking the stator. I have a new spare stator because of false readings I got without making good contact in the connectors with the test leads.

[78GS1KNH]

I sat there for the better part of 30 minutes checking and rechecking the resistance between legs... 0.0 came up with every single leg i tested between the three.

[rustybronco]

78GS1KNH, have you measured the a.c. voltage of the stator with the bike running as of yet?

[78GS1KNH]

No only because i still am in the process of tuning and can't keep the battery charged enough to get good reads from the carbtune and the idle mixture.. THis is how i determined that my regulator was bad, as it was pushing nothing to the battery. Checked the connections and the regulator at 5krpm when i was looking into which piece could be the culprit, and the regulator was definitely bad, as it was pushing nearly nothing to the battery for charging voltage . I then looked into whether or not there was a short across the legs of the stator because of the failed regulator, and sure enough A-B showed 0.0, A-C showed 0.0, and B-C showed 0.0.

[rustybronco]

And we are to 'assume' your meter is working correctly?

what resistance readings do you get between the legs of the stator and ground?

you can always pull the cover and take a peek at the stator.

[78GS1KNH]

lol, It has yet to fail me

I'm going to pull the cover hopefully this weekend to check and recheck my readings.
Time to get another bottle of locktite! I am though pretty sure the thing is dead. like paperweight dead.
